On the newer version of Uconnect, wireless Android Auto and I believe Car Play is now supported. On my Uconnect 5 with my Samsung s21, Bluetooth is used for telephone and text but WiFi is used for the balance of Android Auto features.
OP, look at Andriod Auto as your phone has been extended to your vehicle's screen and steering wheel controls. It is not a mirror of your phone. You can configure Andriod Auto and select what apps will be shown on the vehicle's screen. I use Waze and Google maps primarily over the sucky built-in TomTom navigation system. As far as phone calls, text messages, or Google Assistant, you can use steering wheel controls. I'm still adjusting to Android Auto but as I do, I'm liking it.
So far the only negative I have is with navigation. Using Waze or Google maps, the turn instructions that the factory nav provided in the DIC or in the HUD isn't there.
